Definition Human enhancement refers to the application of science, technology, and medicine to augment human capabilities beyond what is necessary for restoring or sustaining health. These enhancements may target physical, cognitive, emotional, or sensory functions, and can be achieved through methods such as pharmaceuticals, genetic modification, cybernetic implants, wearable technologies, or surgical procedures.
Overview Human enhancement encompasses a range of interventions aimed at improving human performance, longevity, or well-being beyond species-typical norms. It is distinguished from therapeutic medical practices, which focus on treating or preventing disease. For example, while a prosthetic limb that restores mobility to an amputee is considered medical treatment, a prosthetic designed to enable superior strength or speed may fall under human enhancement.
The concept intersects with various fields including bioethics, biotechnology, neuroscience, and transhumanism. Applications include cognitive enhancers (e.g., modafinil for improved alertness), gene editing (e.g., CRISPR for potential enhancement of physical traits), and brain-computer interfaces (e.g., Neuralink for augmenting communication or control abilities).
Debates surrounding human enhancement often address ethical, social, and regulatory concerns. Key issues include equity of access, potential coercion (e.g., workplace demands for cognitive enhancement), long-term safety, and the philosophical question of what constitutes "natural" human functioning.
Etymology/Origin The term "enhancement" derives from the Latin root "hac, hanc, hic" through Old French "enhancier," meaning "to raise" or "improve." In the context of biology and medicine, "enhancement" began to be used in the late 20th century to describe interventions that exceed therapeutic goals. The compound term "human enhancement" emerged in academic and policy discussions in the 1990s and 2000s, particularly with advances in biotechnology and discourse around transhumanism.
Characteristics
- Non-therapeutic: Targets improvements beyond normal health or function.
- Multimodal: Can involve pharmacological, genetic, mechanical, or digital technologies.
- Optional: Typically not required for medical necessity.
- Diverse applications: Includes physical stamina, intelligence, memory, emotional regulation, sensory perception, and lifespan.
- Technologically driven: Relies on advancements in biomedical engineering, AI, genetics, and nanotechnology.
